Specification of Letters Patent.

Patented Nov. 7, 1905.

Application filed August '7, 1905. Serial No. 273,103.

To all whom, it may concern:

Beitknown that I, JAMES S. HARLOW, aciti- Zen of the United States,residing at May, in the county of Brown and State of Texas, haveinvented a new and useful Cultivator-Blade, of which the following is aspecification.

This invention relates to cultivators, and has for its object to provideblades connected in pairs and embodying new and improved features ofcheapness, durability, and efliciency.

Afurther object of the invention is to provide a blade for cultivatorswhich will cultivate the soil with the minimum expenditure of motiveforce.

WVith these and other objects in View the present invention consists inthe combination and arrangement of parts, as will be hereinafter fullydescribed, shown in the accompanying drawings. and particularly pointedout in the appended claims, it being understood that changes in theform, proportion, size, and minor details may be made without departingfrom the spirit or sacrificing any of the advantages of this invention.

In the drawings,'Figure l is a top plan View of the improvedcultivator-blade, showing it applied in gangs to a cultivator. Fig. 2 isa perspective view of one pair of connected blades. Fig. 3 is a view ofthe improved blade in front end elevation. Fig. 4 is a view in sideelevation of the blank from which the blades are formed.

Like characters of reference indicate corresponding parts in all of thefigures of the drawings.

The improved cultivator-blade forming the subject-matter of thisapplication is adapted to be used and applied in a variety of ways, oneof which is shown in Fig. 1, wherein 10 represents oppositecultivator-beams having the usual downwardly-extending standards 11. Inits preferred embodiment the improved blades are mounted in pairs, as 12and 13, formed of plates of metal, having lips 14 and 15 turned at rightangles to the general plane of the plate and secured to opposite ends ofthe strip 16, as by the bolts 17 and 18. The

strip 16 is provided with an intermediate opening 19, through which anyapproved fastening device is inserted, as the eyebolt 20.

Each of the blades 12 and 13 comprises a similar blank, (shown at Fig.4,) being wider at one end than at the other, with the lip 14 atthenarrower end. Intermediate the ends a V-shaped notch 21 is formed in thelower edge, with the rearward side 22 of the notch rounded, as shown,and a similar rounding formed at 23, rearwardly of the lip 1 The loweredge of the section 2A to the rear of the notch is then curved laterallyto one side, while the lower edge of the section 25,

forward of the notch, is similarly curved to the opposite side. Thesections 24 and 25 of each pair of blades are respectively curved andproject to the same side. The lower edges 22 and 23 are reduced tocutting edges and the several pairs of blades mounted to constitutegangs, with similar curves extending to the same side for the entiregang, with the blades of the opposing gang oppositely curved.

From the foregoing description it is believed the use and operation ofthe improved cultivator-blade will be fully and clearly understood.

Having thus described the invention, what is claimed is 1. Acultivator-blade formed of a blank sheet of metal wider at the rear endthan at the forward end and with a V-shaped notch cut transversely inthe lower edge, the metal being curved laterally at its lower edge andoppositely on opposite sides of the notch and having its lower edgesreduced to a cutting edge.

2. In a cultivator, gangs of blades arranged in pairs and each formed ofa blank sheet of metal wider at the rear end than at the forward end andwith a V-shapecl notch cut transversely in the lower edge, the metalbeing curved laterally at its lower edge and oppositely on oppositesides of the notch and having its lower edges reduced to a cutting edge,the said gangs being arranged to throw soil in opposite directions.

In testimony that I claim the foregoing as my own I have hereto afiixedmy signature in the presence of two Witnesses.

JAMES S. HARLOW.
